Another wave power generator is making its way to the European Marine Energy Centre (EMEC) in Orkney, Scotland. Following its testing in Leith, near Edinburgh, ScottishPower Renewables’ new P2 Pelamis wave power device took a two-day oversea journey to join a similar machine, installed at the EMEC last year by E.On. The two P2 Pelamis machines will undergo further testing in tandem, allowing the companies to better understand how an array of devices would operate under real-world conditions. The trials will help the companies design larger commercial systems.
The 180-meter-long P2 uses hydraulic cylinders to convert the motion of waves into electricity. The power generated is then transmitted back to shore by a subsea cable. The P2 is the second-generation machine developed by Pelamis Wave Power, and is expected to be more efficient than its predecessor. A single P2 device can generate 750 kilowatts (kW) of electricity, enough to power approximately 500 homes annually. The construction of the device was partially funded by a grant from the Scottish government’s Wave and Tidal Energy Support Scheme (WATES).
ScottishPower Renewables is also developing a wave energy site at Marwick Head in the Pentland Firth that could host up to 66 Pelamis P2 wave power generators.
“Scotland is continuing to lead the world in the development of wave and tidal energy, with a quarter of Europe’s tidal stream and a tenth of its wave energy potential,” Energy Minister Fergus Ewing said in a statement. “As the last of our WATES funded projects, this is a significant milestone and is evidence that public funding is helping developers exploit that resource, enabling the marine energy sector to go from strength to strength. This latest development further reinforces the growing momentum in marine renewables across Scotland and the breadth of activity taking place at the world-leading European Marine Energy Centre.”
